About this map

Santa Catalina Mountains dominate this 1981 survey of the high-elevation peaks north of Tucson, centered on the summit of Mt Lemmon. The settlement of Summerhaven and the residential area of Loma Linda provide a rare look at the mountain community's layout before later fires significantly altered the landscape. Infrastructure supporting the summit includes the Mt Lemmon Observatory and a network of radio towers and a Heliport, reflecting the peak's importance for both scientific research and communications.

The map details a landscape carved by deep canyons such as Sabino Canyon and Cañada del Oro, peppered with numerous water sources like Wild Cow Spring and Iron Spring. Mining history is represented by the Hartman Homestake Mines near Catalina Camp on the northeastern slopes. The map also delineates the Wilderness of Rocks and the Pusch Ridge Wilderness, showcasing the complex topography of ridges like Sutherland Ridge and unique geological landmarks like Window Rock and Cathedral Rock.
